Instruction
Aluminium alloy 3003 is a medium strength alloy with very good resistance to atmospheric corrosion and very good weldability and good cold formability. This alloy has better mechanical properties even at high temperatures than the 1000 series alloys. This alloy can easily withstand the temperature load in any extreme condition. It also provides excellent stress distribution and conducts electricity. It contains aluminium and manganese elements. Our company produce two types of round bars that is cold rolled and hot rolled. These round bars has good mechanical properties like tensile strength, yield strength, fatigue strength, and hardness. These round bars are mostly used in various applications because it has capacity to bear high pressure without losing their properties.

One of the main advantages of Aluminium Alloy 3003 Round Bars is that they are lightweight. This makes them easy to handle and transport, and ideal for use in applications where weight is a critical factor. Despite their lightweight nature, they are still very strong and can withstand heavy loads and stress.
Another advantage of these round bars is their exceptional corrosion resistance. They are highly resistant to corrosion and can withstand exposure to a wide range of harsh environments, including marine and industrial applications. This makes them ideal for applications where the metal is exposed to water, moisture, and other corrosive agents.
Aluminium Alloy 3003 Round Bars are also very malleable, allowing them to be easily formed into various shapes and sizes. This makes them highly versatile and suitable for use in a wide range of industries, including aerospace, automotive, construction, and manufacturing.
